LUBRICATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 790,498, dated May 23,1905. Application filed December 31, 1903. $erial No. 187,260.

To (all whom it may concern: 7

Be it known that I, HENRY HAMELLE, a citizen of the Republic of France,residing in Paris, France, have invented certain new and usefulImprovements in Lubricating Apparatus, of which the following is aspecification.

This invention relates to lubricating apparatus, and has for its objectto provide a lubricator particularly applicable for the lubrication ofthe mechanism of motor-vehicles. It is so constructed that when thevehicle is stopped the water from the sight-tubes cannot descend.Further, it is provided with regulating mechanism within easy reach ofthe chauffeur.

Figure 1 is a front elevation of my lubricating apparatus. Figs. 2 and 3arehorizontal sections on lines M N and P Q, respectively, of Fig. 1.Fig. 4 is a vertical section on line B S of Fig. 2. Fig. 5 is atransverse section on line T U of Fig. 1, and Fig. 6 is a part-sectionalview illustrating the method of operating the compressing-pump.

- My lubricating apparatus comprises a reservoir A, constituting theoil-tank, formed at the center with a vertical projecting part (4,

provided with a window o to allow of the level of the oil in the tankbeing ascertained. At

' each side of the projecting part a are sighttubes B, arranged abovetwo chambers C, communicating with each other at 0. In the tank A is apump D, which forces oil through a pipe E to astorage-box F, which opensinto one of the chambers C. This pump is operated by a link 6, actuatedby an eccentric f on a worm-wheel G, which gears with a worm g, theshaft of which is provided at one end with a'grooved pulley h, driven byany suitable means from the motor-vehicle. The oil passes through aconduit into one of the chambers (J, fills both chambers, whichare, asabove described, in communication through 0. Thence the oil rises intothe sight-tubes B, which are filled with water, by passing through anaperture j, which opens into a nozzle 70. A central needle or rod Z, oneend of which is within the nozzle, serves to guide the drop of oil whichrises into the water in order to pass through the upper part into thespace m, connected by a conduit 01. with a tube 0, which communicateswith the parts to be lubricated. The upper opening of the sight-tubescan be closed more or less by a valve g on a threaded rod 7, providedwith the said guide needle or rod Z. The chauffeur can easily operatethe knob or button carried by the threaded rod r to regulate as may berequired the flow of oil to any one of the sight-tubes.

Between the chamber G and the nozzle is for the oil-supply is a screw 3,provided with a transverse opening 6. When the screw is screwed down tothe bottom, as shown in the drawings, there is a free passage for theoil. When it is desired to close the communication, the screw is turneda quarter of a turn, and the transverse hole then occupies a position atright angles to the orifice During the normal operation of thelubricator the screw 8 is screwed home and is under the best conditionsof hermeticity.

The oil does not pass directly from the chamber C to the sight-tube, butthrough a tube a, which dips into a cup 1.. This arrangement is providedfor the following purpose: When the vehicle stops, and the oilconsequently ceases to be forced in, the water from the sight-tubestends by reason of its density to descend into the chamber 0 to theretake the place of the oil, which, on the contrary, tends to rise intothe sight-tubes. The result would be that the tubes would become filledwith oil, and upon restarting too large a quantity of oil would beforced into the pipes leading to the parts to be lubricated, therebyentailing a considerable loss of oil. With the arrangement shown alittle water descends from the sight-tubes through the tube u into thecup 7),"

but the descent of the water stops when it reaches the lower end of thetube a.

I claim- 1. In a lubricating apparatus, means for forcing oiltherefrom,a cup through which the oil passes, and a sight-tube having a tubularportion connecting therewith and extending into said cup, whereby toprevent the descent of the water from said tube when said oil-forcingmeans ceases to operate.

2. In a lubricating apparatus, the combination of a sight-tube adaptedto contain water, through which the oil feeds, an upper screw the lowerend of which forms a valve-face, and a guide-rod carried by said screwand extending longitudinally of said tube and down to the lower orificethereof.

3. In a lubricating apparatus, a reservoir formed as a box or tank, asight-tube at each side of one face thereof connected therewith andadapted to receive oil therefrom, said reservoir having a projectingportion on the same IO face and intermediate of said sight-tubes, and

said portion being connected with said reservoir and having atransparent wall through which the level of oil in said reservoir may beobserved.

In witness whereof I have hereunto signed 5 my name, this 16th day ofDecember, 1903, in the presence of two subscribing witnesses.

HENRY HAMELLE.
